File this under "yet another reason to double check an email before hitting send."

The Arizona Department of Revenue accidentally sent out a mass email Monday that included a hyperlink to a pornographic website along with its latest bulletin advertising an auction of unclaimed property.

Roughly five hours later, a spokesman for the agency retracted the email and issued an apology to recipients.

The spokesman said he "mistakenly left a placeholder link using the letters 'XXX' " for a hyperlink in the bulletin, which advertised an auction of safe-deposit box items abandoned for at least five years. (It redirected to a website the address of which will not be printed here.)

Well, that's one way to draw attention to unclaimed-property auctions.

The online portion of the auction ends Sunday at 5 p.m. and it features items such as rare coins, jewelry and comic books. See the items at www.sierraauction.com (yes, we double checked that link).
